Copperleaf is grown for its showy foliage and should be kept in a bright position to allow the strong colours to develop. Most plants will produce small tassels of insignificant flowers during late spring and summer, which should be removed as soon as they begin to lose their colour. Copperleaf can quickly develop into a large shrub, up to 1.8m tall. It should be pruned annually to keep it looking shapely. Cutting back about half of the previous year’s growth should keep the plant compact.
